The second predetermined position may be selected to be a position at which the camera can capture a clear and complete image of the light-transmitting surface.

Only one item 1-3 can be placed in one pair of opposing sorting trays, i.e. only one item 1-3 can be placed in the first and second sorting trays and only one item 1-3 can be placed in the third and fourth sorting trays.

The image of the light-transmitting surface shot by the camera contains images of a plurality of through holes, and based on the requirement that only one object 1-3 can be placed on a pair of trays 1-1 oppositely placed on the plate-turning trolley, if the control system analyzes that the through holes in the image of the light-transmitting surface of the tray 1-1 are blocked, the control system indicates that the object 1-3 is placed in the tray 1-1; if the control system analyzes that the through holes in the light transmission surface image of the tray 1-1 are not blocked, the control system indicates that no article 1-3 is placed in the tray 1-1, and based on the result, the number of the articles 1-3 placed in the sorting tray in the preset time period can be analyzed.
